Trash should be separate for each supported device

I have not found any previous (open or close) issue on this, which seems weird.

Having an unified trash is counterintuitive with many devices mounted at the same time, and emptying the trash to make space on a device is impossible without clearing all Trashes, which is often extremely slow and slightly dangerous.

I believe that, while having a Trash subdirectory in each device would mislead most users expecting, for example, their new drive to be empty and violating the principle hiding the trash directory on all OS, the Trash item of the sidebar should at least show a different "top bar" (the one with Empty and Restore) for each mounted device

Here is the first idea that came to my mind, if it helps to understand better what I mean:
